1 Claim.

Our invention relates to improvements in flush tank and closet bowl combinations.

The object of our invention is to provide means.

for creating a whirling or vortical motion in the bowl to facilitate the action thereof.

We attain these objects by the mechanism illustrated in the accompanying drawings, in which Fig. l is a plan View of the tank and bowl; Fig. 2, a front sectional view along the lines 2-2 of Fig. 1; Fig. 3, a side sectional view along the lines 3-3 of Fig. l; and Fig. 4, a sectional view along the lines 4-4 of Fig. 3.

Similar numerals refer to throughout the several views. 7

The flush tank 1 as shown is mounted upon and, preferably, formed integral with the toilet bowl 2. The invention is not, however, limited to use with this construction, but is adaptable to constructions wherein the tank and bowl are 20 spaced apart as is customary. The bottom of the tank 1 is apertured at 3 to provide communication between the tank and the entrance chamber '7 of the bowl. The wall 4. of the bowl 2 terminates in the well 8. The wall 4 of the bowl 2 is so formed that its juncture with the well 8 does not lie in the same horizontal plane throughout the circumference of the well, the juncture on one side of the well, preferably that opposite the jet 17, being in a lower horizontal plane than on the opposing side, as shown by the dot and dash contour lines of Fig. l and the horizontal plane lines 5 and 6 of Fig. 2. This uneven horizontal contour of the juncture of the wall of the bowl with the well tends to cause a whirling action of the wa- 35 ter, creating a vortex in the well 8, upon the flushing of the bowl, aiding the siphonic action,

similar parts and forms an important feature of the invention.

The bowl 2 has the usual siphon passageway, formed by the up leg 9 and down leg 10. ihe bowl 2 is provided with the usual integral flushing rim 11 having communication with the entrance chamber 7 at 12. The hollow passageway 13 of the flushing rim 11 has a series of rim flush holes 14 punched at spaced intervals therein, at an angle to cause a whirling or vortical action of the water in the bowl.

The entrance chamber 7 has communication with the concealed jet 15, formed to discharge longitudinally of the up leg 9. A branch passageway 16 leads to the tangential jet 17 formed to discharge in a direction substantially tangential to the circumference of the well 8. This jet is adapted to cause a whirling or vortical action of the water in the well as distinguished from the water in the bowl proper, causing any solid matter therein to be drawn toward the center and downward, where it is more readily expelled and where the hereinafter described jet may act directly upon it-to drive it up the leg of the siphon.

The tangential jet l7, discharging into the well and creating the vortex therein, allows the formation of a more powerful vortex than is possible where the vortical action is induced wholly or largely in the water of the bowl. In the latter case too powerful a vortex causes the water to be drawn up too high on the sides of the bowl, and also interferes with the siphonic action of the bowl by admitting air through the center of the vortex to break the siphon. The constant feeding into the well furnishes suificient water to prevent the breaking of the siphon. Jets adapted to create a vortex in the bowl proper have been used in the prior art, but their action is considerably different from that of a tangential jet in the well hole.

It will be understood that the effects of the tangential jet 1'], the angle punching of the rim flush holes 14, and the uneven horizontal contour of the juncture of the wall of the bowl with the well are cumulative, and that one or more 30 of these expedients may be dispensed with, depending on the degree of vortical action which is desired.

A jet supply conduit 18 leads from the tank or other source of water supply to a jet 19 formed 35 to discharge longitudinally of the up leg 9 of the siphon passageway. It will be understood that the number and location of the jets described hereinabove is to a certain degree optional, and that variations in the number or location of the jets may be made without departing from the spirit of the invention.

We claim:

A water closet bowl comprising a side wall, a well joined to said side wall and a siphon discharge passageway having communication with said well, a jet positioned below said side wall and adapted to discharge into said well in a direction substantially tangential to the circumference thereof, the juncture of said side wall with said well being on a lower horizontal plane on the side of the well opposite the said jet than on the jet side of said well.
